French microkernel operating system developer Chorus Systemes SA has come to an agreement with Motorola Inc’s Semiconductor division for joint development and marketing of a combination of the Chorus Unix System V-compliant microkernel technology with the PowerPC chip Motorola is developing with IBM Corp. The two will offer products with the Chorus microkernel embedded on the PowerPC chip, in response, they claim, to demand from telecommunications manufacturers. Chorus will optimise the microkernel for the PowerPC. A development kit for applications developers will be available by year-end, and open microkernel on-chip products will be on the market by the first quarter of 1994. Chorus has a similar deal with Thomson CSF SA for the Inmos Transputer, and plans to team with other chip manufacturers.
